Hi Hans and Carlos
I see that using Carlos's script in 25 above works for html files as well 
One just needs to change the file suffix from .txt to.html 
and get rid of the as text... and excel opens the html file without problem.
'app.Workbooks.OpenText ("C:\\Users\\Trevor\\Desktop\\myHTML.html")\r',
So I guess in apple script one this should work
+ 'open text file filename (POSIX file "' + macFileName + '")\r'
Parsing to text delimited is not an option because in this case I loose the images stored in the indesign table which is exported as an html file.
I see I wont be able to send the link to the script I made until Sunday.
Have a good weekend
Trevor
